A method, that in an embodiment receives a key parameter from a container-managed persistent bean, determines that the container-managed persistent bean is associated with a non-relational data store, creating a web service input message with the key parameter, and invokes a web service function with the web service input message to interface with a non-relational data store. The determination that the container-managed persistent bean is associated with a non-relational data store may be based on deployment description extension settings specified by a bean assembler. In this way, a container-managed persistent bean may be used to access a non-relational data store.
